A 4 kg mass is suspended from by a spring. The spring has the property that a force of 10 N stretches the spring 0:5 m. Let x (t) be the position of the spring at time t: The damping force is equal to 16x 0 (t): The mass is released from the equilibrium position with an initial downward velocity of 4 m/s. Find the position function x (t)

Someone answer this asap rn for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
